Teller Farms - East Boulder Trail and White Rocks Preserve

Boulder - Denver - Golden - Fort Collins - Lyons

The East Boulder Trail stretches 6.15 miles from the Teller Farms – South Trailhead off Arapaho Road to the Gunbarrel Farm Trailhead in the Heatherwood neighborhood of Gunbarrel. The trail passes through the working historic ranch of Teller Farms, White Rocks Nature Preserve, Lower Boulder Creek Conservation Area and rolling hills of a short grass prairie. Groomed trails and mild grades in a bucolic setting make this a 4-season favorite among trail runners, families and birdwatchers.
